What novices need to pay attention to when farming koi fish, and how to raise koi fish for novices

It is necessary to ensure that the temperature is right, and it is necessary to choose the right feeding method, and to change the water regularly, as much as possible to ensure that it is changed twice a week.

In the process of raising koi, it is important to ensure that the water temperature and oxygen are appropriate. In addition, the water source should be changed regularly, as much as once every three days, and attention should be paid to choosing the right feed.

Novices raising koi fish should pay attention to avoid overfeeding, and it is enough to feed once a day. It is necessary to change the water frequently, the water is the living environment of the koi, and it is necessary to ensure that the water for raising koi is free of impurities and no germs. In general, the water should be changed once or twice a week.

When buying a fish tank, you should choose the right fish tank according to the size and number of koi fish to ensure that the koi have enough space to move in the fish tank. <

1. Feeding: Koi fish do not have a sense of satiety, they will eat as much as they feed, and if they feed too much, they are easy to die. Usually once a day is fine. The feed can be bloodworm, carrot, fish feed, etc., and the general fish food on the market can also be fed to it.

2. Water change: Koi fish live in the water, and the excrement and impurities shed by the body will naturally fall off directly in the fish tank. During the maintenance period, it is necessary to change the water frequently to avoid pollution caused by excessive impurities.

Usually the water can be changed once a week, but if the koi fish are sick, they need to be changed every other day.

3. Fish tank: When choosing a fish tank, you should decide which fish tank to use according to the size and number of koi. If it is a small koi, you can use a round tank, and the material can be made of glass.

If you are a large koi, you need to customize a fish tank or use a floor tank. The safety of the ground tank and the customized fish tank is relatively high, which is suitable for breeding large koi fish. In terms of material, it is necessary to choose a material with high hardness.

Koi is a relatively easy to raise fish, the water quality, temperature, food requirements are not high, as long as the water quality is clean, the temperature is guaranteed to be between 20 degrees and 26 degrees, and the food is fed regularly, you can breed normally.

1. Fish tank requirements. If you use a glass fish tank to raise koi fish, the tank body should be relatively large, at least 80 cm or more. Before releasing water in the fish tank, it is necessary to raise water for at least 10 days.

In addition, the fish tank should be equipped with a powerful filtration system, it is recommended that 20% of the space is placed in the filter cotton and biochemical cotton for simple physical filtration, and 80% of the filter tank space is used to put the ceramic ring of the bacterial house, because the metabolism of koi fish is relatively large, so the ammonia nitrogen conversion in the water is more frequent, so more nitrifying bacteria are needed to deal with it.

2. Choose big fish. When raising koi fish, it is best to choose big fish, because small fish have poor resistance and are easy to die if they are not raised well; The big fish has strong resistance and a relatively large fault tolerance rate. Generally, novices raise koi, and it is best to start raising fish between 25 cm and 40 cm.

When we select, we can observe its activity, and we know that koi fish have the habit of jumping. The more robust the koi, the easier it is to jump from the tank, or swim fast and brightly colored, then such a fish is healthy and high-quality.

3. Feeding management. Because koi fish have no stomach, it is generally necessary to eat small and frequent meals when feeding koi, and it is recommended to keep it for about 3 to 5 minutes as much as possible when feeding koi. There are many things that koi fish can be fed, but if you want to raise koi well, you must feed special feed.

Koi feed is generally divided into five types: enrichment, breeding, color, germ and staple food. In addition, koi fish love to eat live bait, but live bait can cause damage to koi. Each feed has its own role and should be fed according to the temperature.

When the water temperature is lower than 20 degrees, it is recommended not to feed the body and color feed; When the water temperature is below 20 degrees, it is recommended to feed embryo feed.

4. Pay attention to water change. Koi carp have strong adaptability to water quality, but it is still necessary to pay attention to changing the water, in addition, koi are most afraid of sudden changes in water temperature, when the water temperature suddenly rises or drops by about 6 degrees, koi may die immediately. Therefore, when changing the water, be sure to control the temperature difference and do not exceed 3 degrees.

In addition, excessive levels of ammonia nitrogen and nitrite in the water can also cause koi poisoning, and in severe cases, it will lead to direct death of koi. If conditions permit, increase the biological filter tank and add more filter media to improve the filtration effect.

5. Disease prevention. Although koi fish are relatively easy to raise, they are also prone to illness. Generally, newly introduced koi fish should be quarantined first, and if conditions permit, it is best to isolate and observe for 1-2 weeks, and then put them into the main fish tank to raise them.

To prevent illness and mild illness**, sea salt is probably the best medicine. If the koi fish are always sick, the reason can be found from factors such as feeding density, filtration system performance, feeding amount, water quality control, and new fish quarantine.

Novice koi fish are as follows:

1. Maintain water quality

Koi do not have high requirements for water quality, and there is a lot of excrement every day, so buy a filter (which runs 24 hours a day) and filter the water quality while delivering oxygen. Generally, the daily consumption of electricity is less than 1 kWh. The frequency of water changes is once a week, one-third to one-half of a water change at a time.

Do not change the water too much at one time, which will cause the instability of the ecosystem in the fish tank, and it is easy for the koi to be unadaptable.

Second, the cleaning of the fish tank:

If you buy the kind of fully automatic fish tank, it is equipped with a cleaning system, and you can change the filter once every half a month or clean it once. However, koi fish are not such complicated equipment, so the fish tank is easy to grow green moss, and the way to prevent green moss is to clean the fish tank frequently.

When cleaning the fish tank, take out all the fish, and keep half of the water so that you don't pour it out, and pour it back after cleaning the fish tank. If you don't have time to clean your fish tank often, you can put it in a cool place away from direct sunlight and put wallpaper on a sunny area.

3. Don't plant aquatic plants:

Now those aquatic plants are very expensive, and if you raise koi, the aquatic plants will be eaten quickly, and the gains outweigh the losses. And eating the leftover residues can easily pollute the water quality. My method is to raise aquatic plants in a separate pot and regularly add aquatic plants to the tank to replenish nutrients.

Fourth, the control of water temperature:

If the weather is particularly cold, pay attention to putting some nutritious fish feed to supplement calories. If the weather is particularly hot, feed less food, clean the fish tank more, and change the water more. When changing the water, pay attention to the water temperature, if you suddenly put the koi fish in cold water, it will be difficult for it to adapt, so put the water in the basin to cool for a while, so that the water temperature and temperature are about the same before pouring it into the bathtub.

5. Food: Koi fish are omnivores, crickets, earthworms and other insects can be eaten, and vegetarian foods such as bread crumbs and steamed buns are no problem. In short, it eats basically everything you eat. If you feed a lot, you should change the water frequently, and the more you feed, the worse the water quality will be.

How much feed is appropriate for a fish? The general standard is that after you feed the koi, the koi will eat quickly, and you will feed a little more. If the koi haven't eaten within 5 minutes, you've fed a lot.

Sixth, the irradiation of the light:

Koi do not need special lighting, but for sterilization, you can also buy those that have a sterilizing effect and leave them on for an hour or two at night. Of course, this is not to say that this lamp is ineffective (some hospitals also use this principle to sterilize), but I can't see it.

7. Pond and tank culture:

1. Pond culture. The main difficulty of pond cultivation is that not everyone has the space and reasonable conditions for pond farming.

2. Tank culture. The main difficulty of tank culture lies in the oxygen supply filtration, and the water change needs to be changed slowly, because the tank does not touch the ground like the pool and the amount of water is large, and the water change is easy to cause large changes in water temperature, resulting in the weakening of the koi fish's cold physique.

It is recommended to raise a bare tank, because the koi is an artistic painting, the aquatic plants will be eaten up by the koi, and other rockeries take up space, adding some alkaline coral stone or volcanic stone is not for decoration, but alkaline properties make the color of the koi better and the body is healthier.

When raising fish in the family, the cement pond should be soaked to remove alkali, change the water and raise the water, and it is best to put it into the thick green water for a few days (the purpose is to accelerate the growth of moss) before raising fish.

After transporting the koi fish, the protective layer (mucus) on the surface of the fish body is easy to be bruised and damaged after long-distance bumps, and the water in the original plastic bag must not be poured directly into the feeding pond after long-distance transportation.

After entering the house, the koi do not feed on the first day, do not feed or feed less on the second day, and the amount of feeding in the future should depend on the principle of gradually increasing the appetite of the koi, which will help the water quality to not be easy to deteriorate and turn green soon, and do not fall off at one time, which seriously affects the health of the koi.

If the above does not solve the problem, please see:

The plastic bag must be rinsed and cleaned with water first, and then the whole bag of hairtail fish must be put into the pool.

Koi are omnivorous fish and can be fed either animal or plant bait. However, in order for koi to be colorful, in addition to water quality factors, it is more important to feed high-nutrient special koi fish to enhance the color.

In spring and summer, the feeding should be gradually increased from a small amount, and plant feed should be fed as much as possible.

River and lake water, well water, spring water, tap water. The water is filtered and ready for use.
